Kourtney Kardashian and longtime boyfriend Scott Disick are finally ready to walk down the aisle, as a source close to the family tells Entertainment Tonight that a wedding for the couple is "imminent."

The ceremony will reportedly be very small and private -- the complete opposite of sister Kim's extravagant nuptials, and it may even take place at the Kardashian family home in Calabasas.

Earlier today Kourtney and Scott announced that they are expecting their second child together, and they already have one son, Mason, born December 14, 2009.
